Old wood, plaster. and nails will be hard on any drill bit you
get. You can go through 3 to 5 of those paddle bits for the cost
of a good ship auger or a Milwaukee hole hawg spur bit. Kinda
depends on your needs. You will probably not be able to sharpen
either, but a file will touch up the cheap paddle bits without
needing to know much about sharpening.

Irwin has a new, very aggressive bit that is impressive:

I just burned up 2 good quality blade type wood bits in this old
house I am rehabbing (very hard wood and nails)trying to drill
holes for running my electrical. My guess is to just get a 5/8
metal bit. Any recommendations on what would work better?
Thanks.
